' Leners Patent No. 95,092, anal Salimbeni, 1869.

The Schedule referred. toixi these Letters 1atent and making part of thesame.

To all whom it fu1/y concern: j

r Be it known that I, GEORGE CBOMPTON, of Worces- J ter, in the coiintyof Worcester, and State of Massal chusetts, have invented ImprovementsinLooms; and

I dohereby declare that thefollowing, taken in connection with thedrawings` which accompany and form part of this Sp'ecication, is adescription of my invention,.sui`cient to enable those skilled inthe-artyto practise it.

My presentinvention" relates particularly to the organization of thedrop-boxmechanismand shipper", i mechanism of that class of fancy-loomsin which the boxes are distributed, as indicated, by a singlepatternchain or cylinder, by meansof sets of tappets on'a tappeti-shaft,one tappet yraising or lowering the boxes one space, andanother tappetlmoving the boxes a double space, s o that any one of the threeboxesfmay begained at will. l

M'y improvement consists in combiningwith thel tappet-shalt, and the twotappets at each end thereof,

. two auxiliary ratchets and pawls and an auxiliary tappet-workin gshaft, geared to the tappet-shaft, by means of whicllmovement may beimparted to each or either of the tappets at theopposite end of theshaft, such l movement being independent ofthe movements imparted tothetappets adjacent to the ratchets; yand The invention further consistsin the peculiarorganivnation Aof the belt-Shipper mechanism.

, Thedrawings representa loom or loom-frame with my improvementsembodied thereupon.

A shows the loom in end elevation. Y `B is ,aside elevation, showing thebox-actuating mechanism at the opposite ends of the loom', the centralpartsof the frame, shafts, beams, and lay vbeing parts being brokenaway, asv at 15,) showing the boxactuating-mechanism in plan.

a'denotes the frame. b, the lay. 4 v c, the crank-shaft that operatesthelay,

d, the cam-shaft that operates thepawls which actnate the ratchets ofthe tappet-Shaft e, `whose tappets ,effect the changes of the boxes.`

This tappet-shaft carries, at one end, two tappetwheels, fg, and; .atthe opposite nd, two other tappet-wheels, h t', each set of tappeteffecting the move- I ments of the set of boxes, k, on the correspondingend j of the frame.

Each set of boxes is supported 7upon anvertical rod, l, at the end of alever, m, fnlcrnmed at n, a pin projectingfrom the'opposite end ofthelever being pressed np toward or against the peripheries of the twotappets at the corresponding end of the ltappet-shaft. l Thetappeti-shaft @carries four ratchets, o p q fr, one

`opposite end of the lay.

for each tappet; and ywith each ratchet engages, at

proper times, a pawl, s, pivoted in a swinging carrier, `t, which isthrown forward by the cams on thecamshaft, and backy by a suitablespring.

Each p awl is hung to-a linger, u, resting upon a pattern-chain orcylinder, o, eachl pawl-finger holding its pawl above its ratchet, orletting it down into posivtionV to turn its ratchet' at the forwardmovement of the pawl-carrier, as may be determined by thepatternmechanism.

All the ratchets but one are loose upon the tappetshaft. l

The outer loose ratchet, o, is-fixed to the outer tappet-wheehj; and thenext tappeti-wheel, g, is ixed to the adjacent ratchet 1),"(which alsoturns upon the shaft-Q and, as vthe lever-pin under these two tappetspasses from the larger tothe smaller radil'1s.(or

, versa) of the "smaller tappet, it eects a movement of theboxes onespace,l while, when it passes from the larger to the smaller radius (orAvice tersa) of the larger tappet, it ei'ects thernovement ofthe boxestwo spaces, so that by means of the `two tappets, either box of thesetof boxes at this end of the loom can b'e brought opposite the race.'v

The third ratchet, q, is fast upon the shaft, as is also one ofthetappet-wheels at the opposite end of the shaft, so that movement of thisratchet by its pawl effects the movement of the said fast tappeti-wheeland corresponding movement of the shuttle-boxes at such As,'in -order tomake the other or fourth tappetwheelindependentin its movements from thelast-named tappet-wbeel, it ,and its ratchet fr must both be loose uponthe shaft, an intermediate mechanism is neces- Sary for transmittingmovement to it. from its ratchet fr, which mechanism is as follows:

Fixed .to the ratchet 'r is a gear-wheel, w, which meshes-,into'anddrives a gear, so, fixed on one end of an auxiliary shaft, y, at whoseopposite end is a simi-V lar gear,f.z, meshing into and driving a gear,j, lixed to the fourth tappet-wheel, movement imparted to thefourthratchet being thereby transmitted to the fourth to 'those at theopposite end thereof, as relates to the movements of the boxesaffectedby them.

a? denotes the shipper-fork, mounted on a rockeri arm, b2, and fixed toone 'end of a connecting-rod, o?, whose other end is jointed to one armof a bent lever,

d2, pivoted upon a .bracket extending from the frame la, the other armof this lever having a slot, e2, in which .vorks a'pin projecting from aVertical shipper-lever, f2, at one end ofthe frame a, the upper part ofthis shipper-lever travellingrin a guide-slot, g2, at one end of whichit is retained by a notch, h2, except when released from such notch,when it is carried to the opposite end of the notch by a suitablespring.

Turning in bearings at the end of the frame a, at the bottom of thebreast-beam, is a rocker-shaft, e?, on the end of which, next to theshipper-lever, are two arms, k2 P, while, at the opposite end of thebeam, said shaft carries a handle, m2.4

The upper arm k2 projects toward the shipper-lever, and, by pushing thehandle fm2 toward the frame, said arm pushes the lever out from itsstop-notch, the lever then springing down to the end of its slot,thereby turning the bent lever d2, and knocking ofi' the l shipper-fork.

The arm l2 projects down from the shaft infront of a nger, n2,projecting down from. the outer end of a lever, o2, whose other end ispivoted on the under side of the breast-beam.

Just inside of the end-piece of the frame a, a projection, p2, extendsdown from this lever, as seen at D and E. When the dagger on the laystrikes this projection, it 'pushes back the linger n?, causing thefinger to press against the arm l, projecting down from the shaft 112,thereby turning the rookershaft, and causing the upper arm k2 to pushthe shipper-lever fron] its notch, and knoekiug off the loom.

The shipper-lever is drawn back into its n'oteh,from the opposite end ofthe loom, by means'of a hook, 'f l, at the end of a rod, 12, runningunder the breast-beam, and jointed, at its opposit'eeud, to ahand-lever, s2, by Working which the hook is drawn back., bringing withit the shipper-lever, the latter springing into its notch when it comesopposite thereto.

I claim, in combination with a box-indicating pattern-mechanism at oneend of the loom, and with two tappet-wheels and their. ratchets at thesame end of the loom, and loose upon the tappet-shaft, the two o2,substantially as described. n
